Acryloxyethyl-trimethylammonium chloride (Q) was the cationic monomer selected to prepare synthetic copolymer due to the presence of ammonium quaternary group which allows good hydrophilicity for aqueous applications with multiples points of interactions [27], Polymers containing this group have several advantages, including environment stability, low toxicity, lack of skin irritation and excellent cell membrane penetration properties [28, 29], Complementarily the incorporation of N-vinyl-2-pyrrolidone (VP) units is motivated by the idea of providing more stability to the system, considering that the amphiphilic character of VP provides excellent route for the preparation of materials with adequate hydrophilic/hydrophobic balances.

We use N-methyl-2-pyrrolidone (NMP) in combination with N-vinyl-2-pyrrolidone (NVP) since the first additive prevents the overmodulation and this improves the electrooptical response of the device.
There is currently a tendency in the coating of textile yarns to move away from the use of polymers of natural origin, such as starch gum, and an increase in the use of synthetic polymers, such as poly(N-vinyl-2-pyrrolidone) (PVP).
